TERMINAL POST.

Application iled August 3, 1925. Serial No. 47,995.

T o all 1li/0m t may concern.'

Be it knownthat I, EDWARD L. AIKEN, a citizen of the United States,residing at East Orange, in the county of Essex, State y of New Jersey,have invented certain new and useful Improvements in a Terminal Post, ofwhich the following is a descrip.

tion, reference being had to the accompanying drawing, and to theiguresof reference marked thereon.

This invention relates to a terminal post for use in connection withelectrical apparatus and vit is the principal object of my invention toprovide a terminal postto which electrical connections may be quicklymade.

Another object of my invention isto provide a terminal post which willtake either a stra-ight wire, terminal, or the ordinary spade clipcommonly used in electrical circuits such as are found in telephoneandradio work.

Another object of my invention is to provide a terminal which is simplein construction, cheap to manufacture, yet one that will provide a goodelectrical contact and hence be elicient in'operation.

My invention will be best understood b yreference to the drawing inwhich- Figure 1 is an assembled view v01:1 an enf. larged scale of theterminal post attached to a mounting plate and showing a spade clip`held by the terminal.

. Figure 2 is a section on the line 2 2 of lFig. l'with the plungerdepressed.

Figure 3 is a view of the of the terminal post.

In the drawing l is a thimble having slots 2 and 3 substantiallydiametrically op osite. Mounted within the thimble 1 is a pus button orplunger 4 having an end-protruding through the other part of thevthimble. The plunger-4 has a pair of annular flanges 5 and 6 spacedapart so as to provide an annular groove 7. The plunger 4 is normallyheld by the spring 8 so the flange 5 is against the spun over portion 9,atthe upper end of the thimble 1. When in this position the flange 6closes the slots or grooves 2 and 3 thereby keeping dust and dirt out ofthe thimble. Y

As shown in Fig. 1 the plunger 4 has been depressed a certain amount sothat a spade clip 10 can be inserted through the slots 2 and 3,straddling the portions 11 of the thimble and the spade clip 10 isgripped bepush button part tween the flange 6 and the wall of thethimble 1. It will be observed that spade clips of varying thickness maybe yinserted across the slots 2 and 3. It will also be observed that astraight terminal or a conducting wire itself maybe passed straightthrough the slots 2 and 3 and the annular groove 7, on, either or bothsides of the stem portion 12, or, the wire may be attached to theterminal post by laying it edgewise in either one of the slots 2 or 3,the same `as one side of thespade clip. It will also be` seen that boththe spade clip and a straight terminal or wire may be simultaneouslyused. The thimble 1 is preferably provided `with an integral stem 13which is threaded for the purpose of attaching same to the mountingplate as by means'of nuts 15.

Having thus described my' invention what I claim is:

1. A terminal post comprising; a thimble having means for mounting, saidthimble vhaving a pairk of substantially opposite horizontal slots-cutting through the wall Yof the thimble, a plunger held within thethimble but having anl end protruding therefrom, said plunger having apair of flanges disposed to form an annular .groove therebetweenofgsubstantially the width of the thimble slot and a spring within thethimble cooperatingwith the thimbletoV normally hold the plunger so thelower flange 'thereon closes the slots in the thimble.

2. A terminal Apost comprising; a thimble' having means for mounting,said thimble having a pair of substantially op osito horizontalslots-cutting through the wall of the t imble, a plunger held within thethimble ut having an end protruding therefrom, said plunger having apair of parallel flanges spaced from each other a distance sufficient totake the ordinary spade clip y,or wires of varyin diameters within agiven range .and which may be passed through the slots in the thimbleand a s ring within the thimble acting against tlle inner end of theplunger.

3. A terminal post comprising; a thimble havingv means for mounting,said thimble usf having a pair of substantially opposite horizontalslots cutting through the wall ofthe thimble to a distance such that thespace between the slots is such as to allow a standard spade clip tobridge the thimble, a plunger held within the thimble but having an endprotruding therefrom,V said plunger having at least one flange adaptedto normally close the slots but to grip the spade clip after the plungerhas been moved so the s ade cli can e inserted in the slots an a spri gwithin the thimble acting on the plunger for the purpose described.

4. A terminal post comprising; 'a thimble having means for mounting,said thimble v having a pair ofsubstantially opposite horizontal slotscutting through the wall of the thimble, a plunger held within thethimble but having an end protruding therefrom, vsaid plunger having apair of s aced flanges arranged so that when the p unger is depressedthe space between the flanges may be brought into alignment with saidslots whereby a straight conductor may be passed all the way through thethimble between the flanges or a spade clip may be passed across theslots between the flanges and a spring within'the'thimble to react onthe lunger to cause either the conductorl or c 1p to be gripped betweenone of said flanges and the thimble.

5. A terminal post comprising; a thimble having means for mounting, saidthimble having a I air of substantially opposite horizontal s otscutting through the wall of the thimble, a plunger held within thethimble but having an end protruding:

therefrom, said plunger having' a pair of parallel horizontal anges, thelower of, which normally closes said slots in the thimble, the distancebetweerl the flanges being substantially the width of' the slots so thatwhen the plunger is depressed a spade 6. A terminal post comprising; athimble having means for .mount1ng, said thimble having a pair ofoppositely disposed parallel arcuate slots in the wall thereof, aplunger held within the thimble but having an end protruding therefrom,said plunger having Aa pair of flanges disposed to form an annulargroove substantially parallel to said slots and preferably at least aswide as the slots and a s ring within the thimble and cooperatingtherewith to normally react on the plun er.

In testimony whereof I affix my signature.

EDWARD L. AKEN.
